Description

Titan sudoku is a free sudoku game with 36,000+ puzzles.Sudoku originally called Number Place, it is a logic-based, combinatorial number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 sub-grids that compose the grid (also called "boxes", "blocks", "regions", or "sub-squares") contains all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a unique solution.

Completed puzzles are always a type of Latin square with an additional constraint on the contents of individual regions. For example, the same single integer may not appear twice in the same row, column or in any of the nine 3×3 subregions of the 9x9 playing board.

Very very hard on the eyes I loved how the swirls happened but my eyes feel stained after 10 min. The numbers that are highlighted are not distinct enough so I'm staining to pick them out. Otherwise a fantastic game. Love the company Titan.
